Patent DE-3609293-A1 (DE)
Title: Self-locking differential, in particular for motor vehicles
Inventor: SCHMID LEOPOLD F
IPC: F16H48/20
Filed: 1986-03-19
Abstract: In order to provide a self-locking differential in which the spreading forces brought about by the tooth engagements between the differential bevel gears and the axle shaft bevel gears are converted into a considerably larger locking effect than is possible with present-day embodiments, a new and hitherto unknown involvement of the differential bevel gears in the generation of the locking effect is proposed, this involvement being such that the locking effect rises both with the increase of the torque and of the travelling speed, this being the ideal. Differentials according to the invention thus automatically contribute to directional stability, improving the straight-line stability of motor vehicles with increasing speed and reducing sensitivity to side winds.

Title: Clock generator for a phase locked loop having two operating states
Inventor: SCHMIDT HERBERT
IPC: H03L7/08
Filed: 1986-07-25
Abstract: The clock generator is itself constructed as a phase locked loop which interacts with a signal source (3) for a reference clock signal (REF). It contains a variable frequency, controlled oscillator (42) for producing a regulated output clock signal (VFT) which, in the synchronised state, is synchronised to the reference clock signal, a phase comparator (41) for comparing the reference clock signal with the output clock signal, and a loop filter (43). In order to differentiate between the synchronised state and a further operating state, a switching device (2), which is controlled by a steady state switching signal (ST-N), is provided, having two inputs which can be selectively switched through to a common output. The reference clock signal (REF) is supplied to one of these two inputs of the switching device (2), and the output clock signal (VFT) is supplied to the other input, via a delay element (5). The output of the switching device (2) is connected to that input of the phase comparator (40) which is allocated to the reference clock signal (REF). In consequence, the output clock signal (VFT) is regulated to the reference clock signal (REF) in the synchronised state, while its frequency is continuously reduced in the other operating states. Such a clock generator is suitable, inter alia, for use as a clock generator for producing the reference clock for a digital phase locked loop for data recovery in the case of high-performance magnetic tape recorders. <IMAGE>

Patent DE-3635109-A1 (DE)
Inventor: HIRSCHMANN WALTER
IPC: H05B39/04
Filed: 1986-10-15
Abstract: To permit dimming of a halogen incandescant lamp, or set of lamps connected to an electronic transformer circuit which receives operating voltage from a power network, rectifies the current supply and chops the rectified power to provide high-frequency alternating voltage for transformation to low voltage of the incandesent lamp, a non-current compensated choke having an inductance of at least 50 mH is connected in series between the rectifier output terminals and the rectifier system terminals, an oscillation start acceleration circuit including a CR circuit is connected in parallel with the starting circuit for the alternately operating transistors and a pair of symmetry resistors (R6,R7) are connected in parallel to symmetry defining capacitors (C6,C7), connected across the rectifier output terminals and a mid-point (M) of the oscillation transistors. The arrangement permits soft starting of the transistors, even if a serially connected phase controlled dimmer circuit suddenly connects line voltage at peak value across the rectifier, while providing for continuous energy release, even if the dimmer control is turned beyond the 90 DEG  phase angle position and, for example, to 135 DEG phase angle.

Patent DE-3701579-A1 (DE)
Title: Process for the preparation of pastable vinyl chloride polymers by continuous polymerisation in aqueous emulsion
Inventor: BOEKE BURKHARD DR
IPC: C08F14/06
Filed: 1987-01-21
Abstract: According to the relevant prior art, i.e. in the continuous polymerisation with predispersion, pastes are formed which result in flexible PVC with excessive fogging, due to the presence of long-chain alcohols. The viscosity behaviour with time is also unsatisfactory, and the amount of emulsifier used is still too high. According to the invention, the predispersion is prepared using oxyethylates or oxypropylates of the long-chain alcohol. This causes a noticeable reduction in fogging and emusifier consumption, and the viscosity of the pastes is initially independent of time. The polyvinyl chloride is used for the preparation of pastes from which flexible PVC and flexible foams are produced.

Title: Device for the assembly and dis-assembling of vehicle spring struts
Inventor: TOPP ROLF
IPC: B25B27/30
Filed: 1987-02-19
Abstract: The device serves for dismantling spring struts (26) into their components (shock absorber (25) and spring (28)) or for assembling them. On a frame (10) a support (33) is provided, through which the end of the piston rod (30) of the shock absorber (25) projects, but which does not permit the passage of the spring (28). The annular flange (27) of the shock absorber cylinder (24) presses against the other end of the spring (28). The said annular flange (27) is pushed forward by an adapter sleeve (23). A conventional car jack (20), which is inserted into the frame (10), acts on the adapter sleeve (23). When the car jack (20) is operated, the spring (28) is compressed so that the abutment plate of the shock absorber on the piston rod (30) passes through the support (33) and can easily be removed on the other side of the support. The device is especially suitable for use in garages, in which assembly and dis-assembling of spring struts occur relatively infrequently. It is operated by a standard car jack (20). <IMAGE>

Title: Process for purifying fruit brandies and spirits
Inventor: CHRISTOPH NORBERT WILHELM DR
IPC: B01D3/00
Filed: 1987-02-25
Abstract: Process for purifying fruit brandies and spirits, in which the cyanide in the alcoholic distillate is separated off as completely as possible by chemically binding with electrolytes, and as a result formation of ethyl carbamate in the ready-to-drink spirit is prevented. Cyanide is separated off in the distillate as poorly-soluble silver cyanide, by addition of either a stoichiometrically calculated amount of silver sulphate solution or silver nitrate solution, a silver excess present being coprecipitated as silver chloride by addition of chloride, so that the distillate, after filtration, has cyanide ion and silver ion contents of below 0.1 mg/l and forms at the most technically unavoidable amounts of ethyl carbamate (below 0.4 mg/l). Cyanide is also separated off from alcoholic distillates by contact with electrolytes in the form of anion exchangers in the batch or continuous flow process. Separating off the cyanide is either carried out in distillates which must be distilled once more or in distillates in which a further purification by distillation is not necessary.

Title: Safety distance control device in conjunction with an automatic speed control and hazard warning device without or optionally with intervention by a person, depending on the configuration of the programmed control, for lorries, passenger cars, buses and other vehicles of all kinds
IPC: B60K31/00
Filed: 1987-07-25
Abstract: This safety distance control device is intended to permit a conventional, fully electronically controlled antiblocking system for passenger cars, lorries and buses to be controlled automatically in open-loop and closed-loop fashion. This device is controlled via microprocessors in the processing computer (black box) which serves as the basis for the safety distance device in conjunction with a speed measuring device, a distance measuring device and a hazard warning device, with or without intervention by the driver. In particular, this device is intended to detect automatically a hazard situation so that subsequently a conventional antiblocking system can be controlled with computer speed in conjunction with an antislip system. This permits early detection of a hazard situation so that the safety distance control device reacts in a controlled fashion before the driver can see the hazard at all. As a result, for example rear-end collisions, speeding, leakage losses of dangerous materials and passing dangerous locations with hazardous material without authorisation can be prevented.

Title: House lead-through with steel and plastic pipes for, in particular, gaseous media
IPC: F16L5/02
Filed: 1987-10-28
Abstract: Up until now, the house lead-throughs have been prefabricated for each application and, in addition to a transition piece between the steel pipe and plastic pipe, have further been composed of a steel protective pipe which encloses the plastic pipe in the masonry-wall region of the house. The plastic pipe has had to be composed of a specially profiled head piece. It is proposed to configure the plastic pipe with a uniform profile throughout and first of all to push it beyond the protective pipe fixed in the masonry-wall region, then to provide it, at its end, with a gland nut and to introduce it into a bush which is fixedly connected to the steel pipe. The bush has an internal thread, for the screwing-in of the gland nut, and a seal supported on an inner shoulder. The ready-sealed plastic pipe can be tested for its leak-tightness before it is connected to a connection piece located on the protective pipe, and only then does it have to be connected to said protective pipe.
